No single fixed export rate: monthly excess is credited in kWh; at the beginning of each calendar year leftover credits are sold at the average winter/summer non-firm avoided-cost rate in Schedule 37. Schedule 37 lists 2026 unused-net-metering-credit prices in cents/kWh, but the extracted table does not label the column values in the displayed text.

The state framework sets the default. Where Rocky Mountain Power (WY) pays something different, the utility tariff governs and is what the card above reports.
| Compensation mechanism | Wyoming has no single statewide export rate; compensation comes from each utility's filed tariff. Under Rocky Mountain Power Schedule 135, net energy is credited with the kilowatt-hour credit appearing on the bill for the following month, and any remaining unused credit at the start of the next calendar year is sold to the Company at the applicable Schedule 37 avoided-cost rate. Black Hills Energy applies the same net-metering billing method. |
|---|---|
| Export rate | No single statewide dollar-per-kWh export rate exists. Energy exported in a billing period is credited in kilowatt-hours against the following month's bill; leftover annual credits are purchased by the utility at a filed avoided-cost rate (Rocky Mountain Power Schedule 37, Black Hills Energy Standard Rate for Purchasing Power). |
| Rate effective | Rocky Mountain Power Schedule 135 is effective with service rendered on and after June 1, 2025. Its Schedule 37 avoided-cost update is effective with service rendered on and after April 30, 2026. Black Hills Energy's cited tariff states its $0.02934/kWh payment rate is in effect unless superseded; the reviewed PDF does not expose a net-metering effective date beside that rate. |
| Credit rollover | Yes. Rocky Mountain Power accumulates net excess kWh to offset consumption in subsequent months; Black Hills Energy likewise accumulates net excess kWh for subsequent months. |
| Credit expiration | At the beginning of each calendar year, remaining unused kWh credit from the previous year is sold to the utility at the applicable filed avoided-cost or standard purchasing-power rate; it is not carried indefinitely as a kWh credit. |
| Annual true-up | The annual true-up occurs at the beginning of each calendar year. |
| Program status | The current cited investor-owned-utility tariffs are available for systems of not more than 25 kW; no statewide aggregate cap or statewide successor-rate cap was identified in the reviewed sources. |
| Grandfathering | No enacted 2025 successor-rate grandfathering provision was identified. SF0111, the bill that proposed new-versus-existing customer-generator treatment and a PSC compensation system, failed on third reading in the Senate on February 5, 2025; the current reviewed tariffs instead state their own effective dates and terms. |
| Regulator | Wyoming Public Service Commission. |
| Governing rule | Wyo. Stat. Ann. §§ 37-16-101 through 37-16-104 (Article 1, Net Metering), as cited by the utility tariffs. |
| Pending change | Rocky Mountain Power filed an application to update Schedule 37 for avoided cost purchases of power from qualifying facilities. |
